" ROLLING-PIN.

No. 857,308. I

Patented June 18, 1907;

Application filed March-27, 1907. Serial No. 364,928

. a citizen of the United States, residing at Washington, in the county of Washington and State of Pennsylvania, have invented a v new and useful Rolling-Pin, of which the following is a specification.

This invention relates to rolling pins of that general classemployed by bakers and other persons for'rolling dough and other pastry preparatory to baking the same.

The object of the invention is to provide a rolling pin having a com artment or chamber for the reception of a coo ing medium thereby to maintain the dough or pastry at a sufliciently low temperature toprevent the same from becoming tough when the latter is placed in an oven and baked.

A further object of the invention is provide a rolling pin having a pair of handles threaded on the opposite ends thereof and provided with smooth unobstructed bearing surfaces whereby the pin may be conveniently manipulated without undue friction between the hands of the operator and the terminal handles of said pin.

A still further object of the invention is to generally improve this class of devices so as to increase their utility, durability and efficiency as well as to reduce the cost of manufacture.

With these and other objects in view the V invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, and illustrated in the accompanying drawings, it being understood that various changes in form, proportions and minor details of construction may be resorted to within the scope of the appended claims. I

In the accompanying drawings forming a part of this specification: Figure 1; is a side elevation partly in section of a rolling pin constructed in accordance with my invention. Fig. 2 is a longitudinal sectional view of the same with the supporting handles detached. Fig. 3 is a perspective view of one of the su porting handles detached. Fig. 4 is a si e elevation of a portion of a rolling pin illustrating a modified form of the invention. Fig; 5 is a side elevation illustrating a further modification. Fig. 6 is a longitudinal sectional view of the rolling pin shown in Fig. 5 a

with the handles detached. Fig. 7 is a perspective view of one of the handles shown in Fig. 5 detached. Fig. 8 is aplan view ofthe blank from which the handles shown in Fig. 5 are formed.

Similar numerals of reference indicate corresponding parts in all of the figures of the drawings.

The im roved device consists ofa cylindrical bo y portion 5 preferably formed of glass or other suitable material and provided with an interior compartment or chamber 6 for the reception of a quantity of ice, icewater or other cooling medium, indicated at 7. The oppositeends of the body portion '5 are reduced at 8 and provided with annular flanges or beads 9 and inclined shouldersv 10. One end of the chamber 6 is closed while the opposite end thereof opens through-the adjacent end of the rolling pin and is normally I closed bya suitable stopper or plug 11 which serves to prevent the escape of water or other cooling medium within said compartment.

The exterior walls of the redrfced portions or necks 8 are molded or otherwise formed withinterrupted threads 12 for engagement with corresponding grooves or depressions 13 formed in the walls of the operating han dles 14. v 1

The'handles 14 are'preferably stamped or otherwise formed from a single piece of metal and are each provided with a plural- .ity of spaced notches or recesses 15 defining a series of longitudinally disposed spring T tongues 16 adapted to yieldably engage the opposite ends of the pin, .as shown.

The terminals of the tongue. 16 are bent laterally, as indicated at 17 for engagement with the inclined shoulders 10 while the intermediate portion of said tongues are formed with annular rooves or depressions 18 forthe receptiono? the flange or bead 9, thereby to assist in preventing accidental rotation of said handles on the necks 8 when rolling the dough, pastry or-other material.

Attention is called to the fact that the handle 'adjacentthe open end of the cylindrical body portion 5 forms a closure for the stopper or plug 11 and thusserves to prevent accidental displacement of said plug duringthe rolling operation.

' necks until the grooves 18 engage the flanges or beads 9 and the deflected ends of the tongues 17"bear against the inclined-shoulders 10 thus securely locking the handles in position on the pin and effectually prevent-- ing accidental displacement of the same. In order to refill the reservoir or chamber 6 it is merely necessary to remove one of the handles when the plug maybe quickly detached and the liquid or other cooling medium introduced through the open end of the pin, as will be readily understood.

In Fig. 4 of the drawings there is illustrated a modified form of the invention in which the annular flange or bead 9 is dispensed with, the peripheral threads 12 of,

the reduced necks being relied upon to retain the operating handles in position on the -body portion.

A further modification is illustrated in Figs. 5 to 8 inclusive. In this form of the device the exterior walls of the necks 8", be tween the annular flanges or beads 9' and the adjacentends of the body portion are smooth and devoid of threads and adapted to bear against the correspondingly smooth interior walls of the operating handle 14.

The operating handles shown in Fig. 5 of 7 the drawings are each referably formed of pair of spring arms ada a sheet metal blank 19 t e longitudinal edges of which are cut away 'at 20 and the opposite ends thereof bent laterally to form a ted to engage the exterior Walls of the neo said spring arms being connected by an intermediate web 2-1 by means of which the rolling in may be conveniently hung on a nail or ot er suitable su port when thepin is not in use.

of glass it is obvious that the same may be formed of metal, terra cotta, porcelain or other suitable material andthatthe pins may be made in various sizes and shapes according to the use for whichthey are designed.

From the foregoing description it will be seen that there is provided an extremely simple, inexpensive and eflicient de'vice. admirably adapted for the attainment of the ends in view.

The closed ends of the- .contain a cooling medii' n,

gNhile the device is preferably constructed Having thus described the invention what is claimed is:

1. A rolling pin including a hollow body portion having an interior ch amber opening through one end of the pin and adapted to a circumferential flange formedon each end of the body portion a closure for the open end of said pin,

and handles detachably secured to the opposite ends of the pin, and provided with ter-' minal spring fingers adapted to engage the adjacent flanges on said body portion one oflsaid handles forming a housing for the closure.

'2 A rolling pin including a hollow body portion having an interior chamber for the reception of a cooling medium and provided with oppositel disposed flanges the side walls of the b0 y portion at the o posite ends thereof being beveled to form inc med shoulders, and handles secured to the opposite ends of thepin and provided with spaced spring clamping fingers adapted to engage the flanges and shoulders,respectively. I

3. A rolling pin including a hollow body ortion having'its opposite ends reduced to orm terminal" necks, the exterior walls of which are provided with interrupted threads, there being an annular flange formed on each neck at a point adjacent the threads, and handles engaging the threads on the necks and provided with terminal spring fingers for engagement with the annular flanges.

i 4. v A rolling pin having an interior chamber for the reception of a cooling medium and provided with o positely disposed necks the exterior walls 0 which are formed with annular flanges, and handles detachably mounted on the necks and provided with terminal spring fingers for engagement with the flanges, one end of each handle being reduced and provided with smooth exterior walls forming bearing surfaces.

, 5. A rolling pin having an interior cham ber for the reception of a cooling medium and having its opposite ends reduced and provided with annular flanges, the Walls of the pin at said flanges being beveled to form in- IIO.

clinedshoulders; and handles detachably securedto the opposite ends of the pin and provided with spring clamping fingers havmg grooves formed therein for the reception of the flanges and having their terminals bent laterally for engagement with the inclined shoulders of the in.

In testimony lihat I claim the foregoing as my own, I have hereto affixed my signature in the presence of two witnesses.
